Press Release

Continued network investment and software innovation make Limelight
one of the highest-performing CDNs

TEMPE, Ariz.--(BUSINESS WIRE)--
Limelight Networks, Inc. (Nasdaq: LLNW),
a global leader in digital content delivery, today announced that
content can now be downloaded faster and viewers can stream videos at
higher quality thanks to a major upgrade to its global infrastructure.
The advancements deliver breakthrough improvements to performance,
capacity, and efficiency.

Limelight has completed the global rollout of a new and enhanced version
of its EdgePrism OS software that’s designed to optimize user experience
for the fewest video rebuffers, lowest latency, highest throughput, and
superior security. This new software helps boost Limelight’s edge server
capacity by more than 120 percent by maximizing the performance of
Limelight’s server hardware and application suite. As a result, content
can be downloaded faster, and viewers can stream videos at higher
quality while experiencing fewer rebuffers. Customer-provided real-world
data shows a greater than 19% reduction in video sessions experiencing
rebuffers.

Limelight’s global private QoS-enabled network includes more than 80
Points-of-Presence (PoPs) in over 40 metropolitan locations with 29+
terabits per-second of egress capacity interconnected with more than 900
major ISPs and last-mile networks. Unlike traditional CDN vendors that
rely on third-party technologies for key components of their content
delivery infrastructure, Limelight’s ongoing investment in the
development and optimization of every component of its CDN provides
industry-leading performance, even over congested or changing network
conditions.

Other recent advancements and enhancements include:

Faster Servers and Connectivity: Edge servers have been updated
to the latest high-density 1U servers with solid state drives and 50
Gigabit Ethernet (GbE) network connectivity. This hardware update
increases edge compute capacity and improves performance and cache
management while reducing the number of servers deployed.

New EdgePrism DNS: Limelight’srules-based Domain Name
System (DNS) now features intelligent Point-of-Presence (PoP) and
server selection with real-time decision making that utilizes a
constantly updated map of the internet to ensure optimal delivery
performance and throughput for each customer request.

100 GbE Backbone Links: Corebackbone links have been
upgraded to 100 GbE, allowing cache-fill traffic, dynamic content, and
integrated service data to bypass the congested public internet,
resulting in faster, more reliable, and more secure content delivery.

PoP Expansion: Global egress capacity has been expanded by more
than 40 percent by adding 11 new PoPs and completing full upgrades of
20 additional PoPs to address growing market demand for CDN services.

“Even in emerging regions -- where viewers rely on older mobile networks
for video streaming – Limelight is helping customers achieve their most
important business objectives by improving the quality of experience
they deliver to their viewers,” said Steve Miller-Jones, Senior Director
of Product Management at Limelight Networks. “Our ongoing investments in
our network and software are paying off, resulting in greater capacity,
broader coverage, and increased network performance.”
